Will metal keys affect scans?

They can. Keep the tag face easy to touch and test the final key ring or bag placement before ordering in bulk.

What can I encode on it?

Use it for a short URL, basic contact card, app/deep link, or simple text. For long vCards or long URLs, choose a higher-memory chip and test first.

Writable NFC chips can usually be rewritten until locked. Locking is optional and permanent. Typical chip endurance is 100k write cycles; data retention is listed as 10-year data retention.

Only treat it as waterproof, washable, or outdoor-ready if the SKU specs explicitly say so.

What phones work with NFC tags?

Most modern smartphones support NFC. iPhones (7 and later) and most Android phones can read NFC tags without any app.

What is the read range?

Typical read range is 1–5 cm depending on the tag type and phone. Place your phone directly on the tag for best results.

Attach it where a phone or reader can touch the tag face. Metal keys and tight rings can affect scans, so test the final key bundle.

Storage

Setup

Set it up, then test before rollout

1Prepare the link or record: Use a short profile, contact, access, or app link.
2Write before rollout: Encode and test one sample before distributing the batch.
3Test after attaching to keys or bags: Check scan behavior in the real position, not only on a desk.
